Versatile carrier

ABSTRACT

A carrier includes a supporting unit that is amenable to supporting a wide variety of items. The carrier includes shelves and/or baskets as well as a unit that can be used to support large and/or bulky items. The carrier further includes a stabilizer unit as well as a brake unit. Various attachments can also be mounted on the carrier.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the general art of carts and carriers, and to the particular field of hand carts.

2. Discussion of the Related Art

Many work tasks require mobility. That is, a worker must move from place to place to perform a task or multiple tasks. This often requires the worker to transport tools, equipment and/or supplies with him as he moves about. The art contains many examples of tool carriers. However, these tool carriers have several drawbacks.

For example, some tool carriers have limited space. Bulky items, or a great many items cannot be accommodated. A worker may be required to make several trips to complete a single task. This can be wasteful of time and can be annoying to the worker.

Therefore, there is a need for a carrier that can be adapted to carry a large number of items.

However, in addition to carrying a large number of items, a carrier should be adaptable to accommodate a wide variety of items. That is, the same carrier should be usable with small items as well as large items, and items of varying functions, such as wire spools or the like. The inventor is not aware of any single cart that is adaptable for use with such a wide variety of items.

Therefore, there is a need for a carrier that can be adapted to carry a large variety of items.

Still further, if a carrier is supporting a large number of items or bulky items, that carrier should be stable. Thus, once the carrier is set in a location, it should not be susceptible to tipping or moving. While some carriers in the art are stable after they are loaded, the inventor is not aware of any carrier that is both stable and amenable to transporting a wide variety of items and/or a large number of items.

Therefore, there is a need for a carrier that can be adapted to carry a large number and a large variety of items in a stable manner.

Some carriers in the art are so bulky that they cannot be easily used and moved by a small person. Therefore, such known carriers do not have a wide range of uses since there is a limit to the number of people that are large or strong enough to manipulate or control these known carriers.

Therefore, there is a need for a carrier that can be adapted to carry a large number and a large variety of items in a stable manner yet is easily moved and manipulated.

Still further, some operations, such as a welding operation, or a medical operation, may require a wide variety of tools and equipment and may require several trips to assemble all of the required tools and equipment at one location. The equipment may need to be stored in a readily accessible location yet be located out of the way when necessary. Presently-available carriers are not able to carry and/or store a large variety of tools and/or equipment yet be out of the way when necessary.

Therefore, there is a need for a carrier that is amenable to storing a large variety of tools and/or equipment yet is out of the way when necessary.

PRINCIPAL OBJECTS OF THE INVENTION

It is another object of the present invention to provide a carrier that is amenable to storing a large variety of tools and/or equipment yet is out of the way when necessary.

SUMMARY OF THE INVENTION

These, and other, objects are achieved by a carrier that includes a plurality of changeable shelves as well as a section that can carry large and/or bulky items. The carrier also includes an easily applied brake unit as well as an easily deployed stabilizer unit.

Using the carrier embodying the present invention will permit a user to carry and/or store a large number and a large variety of items, from small items and single tools, to large and bulky items, such as large boxes and the like. The carrier is easily and quickly adapted to such variety and will be quite stable when in use or when standing. The carrier is easy to set up and to move and thus can be used by nearly anyone whereby the carrier of the present invention has a wide range of uses and can be located out of the way when necessary.

As can be understood from FIG. 6, the support shelves 320 can also be in the form of a basket 370 if desired to hold other items. The shelves 320 can be mixed whereby some of the shelves 320 include small circular holes 350, some of the shelves 320 include large circular holes 352, some of the shelves 320 include polygonal holes 354, and some of the shelves 320 are baskets 370, the clearance between adjacent shelves 320 can also be adjusted as will occur to those skilled in the art based on the teaching of this disclosure. Such variations are also intended to be included in the scope of this disclosure as well.

A strap or straps 380 can also be used to tie large or bulky cargo to the frame unit 30 using eyelets 270, 272 if desired. Further straps, such as strap T′, can also be used to tie items to the support shelves 320.
